The end is in sight! The current status is: * (1, 2, 3) Are done and merged (Thank you Alp!). * (6) Phab:D5327 done and merged! * (4, 7) Should be fixed in a small patch that I am currently preparing. * (5) Phab:D52816 after 4 and 7 are fixed, this needs some updating, but is on the right track. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15837#comment:8 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Ghc sees rts as a dependency, and sees `hs-libraries: HSrts-1.0 Cffi` in the ghc- pkg database and then adds `-lffi` to the linking command. Further more, bgamari has suggested that we may not be supposed to link with libffi. We build libffi via hadrian but don't generate a .so. Instead we copy the same .a file as as both an .a and an .so for all flavours {{{ | Copy file: _build/stage1/libffi/build/inst/include/ffi.h => _build/stage1/rts/build/ffi.h | Copy file: _build/stage1/libffi/build/inst/include/ffitarget.h => _build/stage1/rts/build/ffitarget.h | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi.a | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi_p.a | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi-ghc8.7.20181126.so | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi_thr.a | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi_thr_p.a | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi_debug_p.a | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi_thr_debug_p.a | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi_l.a | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi_thr_l.a | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi_debug.a | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi_thr_debug.a | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi-ghc8.7.20181126_thr.so | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi-ghc8.7.20181126_debug.so | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi-ghc8.7.20181126_l.so | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi-ghc8.7.20181126_thr_debug.so | Copy file (untracked): _build/stage1/libffi/build/inst/lib/libffi.a => _build/stage1/rts/build/libCffi-ghc8.7.20181126_thr_l.so }}} Though this may work for the .a files, it wont work for the .so. It's an easy fix to also build the .so and copy that instead: * modify `hadrian/src/Settings/Builders/Configure.hs` to use `--enable- shared=yes` when the way is dynamic. * modify `hadrian/src/Rules/Libffi.hs` to copy .so instead of .a when the way is dynamic. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15837#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Hence I will proceed under the assumption that `-lffi` is correct, and the problem that needs to be solved in getting the linker to correctly find the locally built libffi .so file. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15837#comment:17 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
#15837: Hadrian should build dynamically linked ghc binary -------------------------------------+------------------------------------- Reporter: davide | Owner: davide Type: bug | Status: new Priority: normal | Milestone: Component: Build System | Version: 8.6.1 (Hadrian) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D5385 Wiki Page: | Phab:D5327 -------------------------------------+------------------------------------- Comment (by davide): The locally built libffi is bundled with the rts package. As libffi is ''not'' a haskell library, the naming convention is to call the library `Cffi` in `rts/rts.cabal.in` (see specifically the line `extra-bundled- libraries: Cffi`). When ghc is calculating the linker options, ghc sees that `Cffi` is bundled with rts and tries to link with it. The "C" prefix is striped, but unlike haskell libraries a version number is not suffixed (this logic is in `compiler/main/Packages.hs:packageHsLibs`). Hence ghc links with the `-lffi` option instead of e.g. `-lCffi` or `-lCffi-7.0`. This means the linker is looking for a corresponding .so file named `libffi.so`. As per comment:14 it is easy to produce the `libffi.so` file, but it isn't in the correct location at the moment. There are 2 relevant steps that hadrian takes here: 1. After building libffi, copy the .so from `_build/stage1/libffi/build/inst/lib/libffi.so` to `_build/stage1/rts/build/X`. 2. "Install" the .so by copying it from `_build/stage1/rts/build/` to `_build/stage1/lib/x86_64-linux-ghc-8.7.20181205/X` Currently X in 1 and 2 uses a naming convention convention of e.g .`libCffi-ghc8.7.20181126_thr_debug.so`. This naming convention does **not** match ghc's as described before. It seems that changing X to match the ghc naming convention would solve the problem, but is that the correct solution? Changing the naming convention for the static libffi libraries also sounds necessary, but I thought the the static build been working so far. How is that possible? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15837#comment:18 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Note the symlinks: {{{ $ ls -l _build/stage1/libffi/build/inst/lib/libffi.so* lrwxrwxrwx 1 david david 15 Dec 6 10:28 _build/stage1/libffi/build/inst/lib/libffi.so -> libffi.so.7.1.0 lrwxrwxrwx 1 david david 15 Dec 6 10:28 _build/stage1/libffi/build/inst/lib/libffi.so.7 -> libffi.so.7.1.0 -rwxr-xr-x 1 david david 70232 Dec 6 10:28 _build/stage1/libffi/build/inst/lib/libffi.so.7.1.0 }}} == Static This matches hadrians behavior w.r.t static libffi. On that grounds I'm going to leave the static libs behavior as is, but add a note about possible simplification here: only copy a single .a file as we will do with the dynamic version. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15837#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
